So I've got a New Nintendo 3DS with A9LH installed on it so that I can access Hourglass9 before it boots into sysNAND so I can restore my sysNAND backups in case I do any kind of brick. My New Nintendo 3DS's sysNAND is on version 11.0 (USA). However, I have a few questions because I don't entirely understand everything yet: If Nintendo releases a system update and I do update my sysNAND, will the payload that I use to access Hourglass9 always be functional, or will I have to download an updated version of Hourglass9? I installed a .cia file on my sysNAND to access the Homebrew launcher. If a new system update comes out and I update my sysNAND, is it possible that the .cia I installed may not take me into homebrew anymore? Or is it pretty much always guaranteed to work? Basically, can Nintendo stop me from accessing homebrew from my sysNAND on the latest version even with a .cia installed? Is it possible for Nintendo to ever release a sysNAND update that will prevent A9LH from being accessed/used? Is it possible for a system update to totally screw up everything that I've done on my system? Should I even be updating my sysNAND at all now? I want to play games online, but I've heard that there are workarounds even when you're not on the latest firmware. I only ask because I don't know if updating my sysNAND might mess up any of the homebrew .cia files I've installed on my New Nintendo 3DS.
